Australia’s TPG Telecom is also in the running according to Reuters, which said previous interest from buyout houses Providence Equity Partners and KKR had dropped according to sources familiar with the matter.

The business, which is owned by Spain’s ACS, could fetch as much as A$870m ($910m) according to analysts.

ACS is attempting to sell off the asset as well as smaller data businesses Metronode and Infoplex in order to pay down debt.

Bidders are currently working on a Feb. 9 deadline, two of the Reuters sources said.
